Clinton Maintains Ad-Spending Advantage Over Trump

Donald Trump and his allies are spending more and more over airwaves, but that amount is not enough to overcome Hillary Clinton's 4-to-1 ad-spending advantage, according to data from Advertising Analytics.

Through this week, the Clinton campaign has spent $113 million on ads, versus $27 million for the Trump campaign.

When outside groups are factored in, Team Clinton's ad spending stands at $189 million, compared with Team Trump's $50 million.

That nearly 4-to-1 Team Clinton advantage over the airwaves is down from their 5-to-1 edge last month.

In the battleground states, Team Clinton is outspending Team Trump through this week, $160 million to $44 million.
